I'm debating between the Bravo1 or the Rev4 on prop selection. Right now I have a GOD AWFUL Vengeance 21p that can't hold plane for anything as it drops off at about 28mph The thing is I don't know what pitch selection to go with because I can't get good performance figures with my current setup (it has a small chip on one side) The Mercury prop selector is saying a 19p Rev4 with all weights accounted for but I'm leaning towards a 21p.

What do you guys think? Go with the Rev4 at 19p or step up to the Bravo1 at an even greater pitch?

I would love to hear from any big block guys out there or even some 350mag owners as the difference can't be that significant.

I'm not that worried about grabbing every last MPH out of the prop and more concerned with holeshot and lowspeed planing i.e My wife doesn't like to haul ass.

A 19p is going to be way to small of a pitch, and you are going to HATE it.

You motor is the 375HP and wide open throttle should be 4600-4800. This is the range you need to stay in.

My last boat 242BR, had the 496/375HP and I was running a 23p @ ~ 4700rpms. It would run mid 50's...

I have the 496HO/425HP and have 3 props.
#1. Mirage Plus 3 blade 14 1/2 diameter, 25pThis is my favorite..... With this prop I run about 71-73mph @ ~ 5000 RPM, and planes fairly quick
#2. Mirage Plus 3 blade 14 3/8 diameter, 27PThis prop is my least favorite becuase for every pitch you go up, you loose about 200RPM. This prop I can get about 67-70mph @ ~ 4400-4500 RPM.
#3. Bravo One 4 blade 15 1/4 diameter, 26P.This prop I get 70-72mph @ 4900 RPM, but this seems to be a faster hole-shot then top end speed.

The test above was done without using trim-tabs, single person, with GPS and about 500 lbs of extra weight (fuel and driver)

I have a bravo 22p if you decide to go that route, I bought it and decided to stick with the mirage. The bravo 22 helps provide lift in the rear wich in turn helps you plane quicker so they say but I have trim tabs on my boat so don't really need the help planing, but the price was right so I gave it a try. I would probably sell it for a fair price!

I am proud to report that the Rev4 is the best prop I have ever owned. I barely blip the throttle and I'm on plane with 3 adults in the boat. I am seriously considering using the Vengeance as a spare anchor. Thanks for all the suggestions and happy boating!
